l Application filed November 7,1 898. Serial No. 695,748. (No model.)

To @ZZ whom it rit/.ty concern:

Be it known that I, FREDERICK GEORGE CREED, a subject of the Queen of Great Britain and Ireland, and a resident of Glasgow, Scotland, have invented certain new and useful Improvements in Telegraphic Transmitting Apparatus, of which the following is a specification.

It is the Object of this invention to perforate a tape with holes representing the si gn sdot-s and dashes-ot` the Morse and other similar telegraphic codes by means of such mechanism that a single stroke ot any given key will produce at once all the perforations necessary to represent the complete character corresponding to such key and will cause the tape to be drawn forward a distance equal to the length of tape covered by the perforations representing such character plus the space or distance desired to separate this character from that which follows.

The machine can be Operated by means of a keyboard in a" similar manner and at equall speed to `a type-writing machine and that without previous knowledge of the telegraphcode on the part of the Operator.

It is expected by means ofthis invention greatly to reduce the initial delay in preparing messages for automatic transmission by existing and similar systems, to simplify the process of perforation itself, and generally to facilitate the work of automatic telegraphy.

This invention has no connection with any existing systems having for their object the transmission by telegraph of alphabetic lettering, meaningby that telegraph-machines which print the messages on a tape at the receiving-station.

My object is lmerely to perforate messages in the existing telegraph dot-and-dash codes for use in connection with such transmitters as will forward the messages by means of dotand-dash signs to the receiving-station. To secure these results, the machine comprises a set of perforating-plungers sufficient in nu mber to produce by various combinations the perforations which represent the dots and dashes corresponding in the telegraph-code to any given character. These plungers are operated upon in their appropriate combinations by means of levers controlled from the keyboard, which embraces all characters commonly used in telegraphy. Each key when struck plays upon a corresponding lever, which is provided with a notched and toothed combination representing its own character. This lever in turn sends forward the combination by means of certain of two other sets of levers which act directly upon levers set in the carriage which contains the plungers, driving these last levers over the heads of those plungers which are to be used in making theperforations. The piston of an air-engine coming into action at this moment forces these plungers through the tape, which is led through a slot in a die set directly under them. At the same moment a smalltraveler, armed with a set of small'pins, being liberated is thrown backward by a lever connected to spaceengine and arrested at a distance corresponding to the distance which it is desired to draw the tape forward. When the key is raised, this traveler by means ofpins engages a continuous central row of perforations l(with which the slip has previously been provided) and is then driven forward' (carrying the tape with it) to its usual position of rest. The length of tape drawn forward by the traveler-that is to say, the length of the character-spaces-is regulated by a separate set of levers which arrest the traveler at the proper point. These levers are controlled by the same setof levers that control the levers of the plunger-can riage, and therefore by the key itself. By this invention a small lever attached to a key is provided by means of which the `space may be so regulated as to throw any desired number ot' letters into one combination.

In Order to enable others skilled in the art to which this invention relates to understand how same may be carried into practice, I have hereunto appended tive sheets of eX- planatory drawings, in which the same refer ence-letters are used to indicate like parts in the several figures where shown.

Figure l is a side elevation, Fig. 2 a front view, and Fig. 3 a plan, illustrating Amy invention, while Figs. a and 5 are sectional detail views of operatic g air-cylinders and valve for actuating the perforating-plungers and spacing-lever, respectively. Fig. 6 is a detail plan View of bracket carrying the lever IOO connections for working the combination-lever to connect an y number of letters together. Fig. 7 is a sectional plan view of spacing-carrage and connections; Fig. S, a detail side view of combination-lever; Fig. 9, a side view of spacing-frame; Fig. 10, a plan of dieplate; Fig. l1, a view of the perforated tape, with perforations previously formed in the center for drawing tape forward in the machine and also showing example of the manner of perforating the figure 2 by the plungers of the perforator-carriage. Fig. 12 is a side view showing the levers operated when the figure 2 is struck on machine. Fig. 13 is a front View of the rectangular frames and levers D and E detached. Fig. 14 is a plan of spacelevers 71y for regulating the length of space for any letter. Fig. 15 is a front elevation of perforator-carriage F F' F2, operating-levers, and plungers for perforating the tape. Fig. 16 is a sectional view at right angles to Fig. l5; Fig. 17, a plan of same with top F2 removed; Fig. 18, a perspective view to show partitions or saw-drafts for sliding levers f. Fig. 19 is a perspective view of spring-frame lever f'. Fig. 2O is a detail view showing a method of lifting all the space-levers at one time when it is desired to have such an attachment on the machine, while Fig. 2l shows. a detail view of an arrangement for lifting the first or left-hand space-lever when each key is struck.

Referring to the drawings, the machineframing comprises a keyboard X, base-frame X', supported on feet XX, and standards X2 X3 X4 to carry the various parts of the actuating mechanism. The key-levers Z, which may be thirty-seven or more in number, are made of strips of thin sheet-steelV or other suitable metal or material set on edge side by side horizontally underneath the framing X' and fulcrumed at Z', the long ends being spread out fanwise toward the keyboard X and the short ends converging close together are guided in saw drafts or partitions letinto the frame X', each key-lever being provided with a spring a' to return same to normal position each time a character has been struck.

Underneath the keylevers Z is set the frame A, fulcrumed at A' to a bracket on the machine-frame X and having a cross-bar A2, on which the key-levers rest, and also the space lever, the frame being kept firmly against same by means of an adjustable spring A3. The cross-bar or universal bar A2 underruns the whole of the key-levers Z, and no key can be struck without imparting to the frame A a corresponding movement.

An arm A4 is formed on the frame A, to which is secured a link A5 to connect same to the lever A6 for actuating and controlling the valve-rod ZJ of air and space engine B B5, and also the space-lever connections, to be more particularly described.

As seen particularly in Fig. 12, when a key is struck the key-levers Z act on one end of L-shaped levers C within the standard X4,

and these L-shaped levers C push forward and actuate rectangularframes D, guided in saw-drafts in the standard or framing X3 and which are only capable of forward-and-backward movement, but no side action. The pins d on same, acting on levers E, produce the necessary combination wit-hin the perforatorcarriage to allow of the particular perforations being punched according to the vcha-racter struck. The levers Z and C are equal in number, and the rectangular frames D and E are preferably twenty in number to produce the combinations required for the various characters of the telegraphic system in use.

The vertical or upright arms of the L- shaped levers have teeth or notches cut on them for the purpose of producing thel combination above referred to, the teeth c pushing forward the rectangular frames D, while the notches c2 allow of the remainder not required to remain passive. The ends of L- shaped levers C are guided in saw-drafts corresponding to those that guide the key-levers. These rectangular frames D have pins d, as above described, to act on the levers E for actuating the levers and rods or pins ff2 in the perforator-carriage, the pins being distributed diagonally across same, as indicated in Fig. 13, and it will be seen that the pin on first or bottom rectangular frame D makes contact with the iirst or left-hand straight lever E, and so on to the last or top rectangular frame D on the right hand. These levers are fulcrumed at e and are capable of forwardand-backward movement and are guided by saw drafts or partitions c', as seen in Fig. 1. The perforator carriage (shown fully in Figs. 15 to 19 of the drawings) is composed of a central casting F, having saw-drafts forv sliding levers f,with side guide-frames F' and top cover F2, with connection for securing to the piston-rod BX of the engine. The pilingers g pass through holes in the central casting F, and the rod F3 for bringing back these and also controlling the extent of travel runs through the groove F4 and is secured in the frame Xzof the machine. The perforatorcarriage is also guided within the standards X2 by V-shaped pieces formed or secured to the central casting F, and the side guide- .frames F', that support and guide the rod or rods f2, and levers f3 for actuating the sliding levers at opposite end of carriage from the levers E are secured to same central casting, as also the spring-frames f' for bringing all back to their normal position.

The engines for operating the perforatorcarriage and also the spacing mechanism,

Figs. 4 and 5, consist of ordinary double-action pistons B2 B4, actuated by compressed air or other fluid and controlled by means of, f

the hollow piston-valve b. The air is led into the valve by the feed-pipe b5, which ends in an adjustable half-collarb, by means of which all Wear can be taken up simply by adjustment of the nuts 12' bs. Through the valve by the port bx it passes into the main engine B by way of either of the ports b2 b2 in valve, to the ports b3 or b4, respectively. From the cylinder of the main engine it enters by the leads b9 bw to the space-engine B3. The spaceengine exhausts into as it feeds from the cylinder of the main engine B, which in turn exhausts directly into the air through either of the ports b3 and b4, respectively.

The perforator-carriage shown (indicated in Figs. 1, 2, and 12 and fully illustrated in Figs. 15 to 19) is set under the engine B within the standards X2 and is capable of vertical reciprocating motion. The carriage is in such a position that the projecting ends of the slid ing levers f (preferably twenty in number, ten on each side, as .seen in Fig. 17) on the one side are directly in front of and make contact with the first out of every pair of the straight levers E, beginning at the left, and the other ten make contact through the pinsf and levers f3 with the alternate straight levers E. By way of illustrating the action of above the sliding leverf (marked 2) touches the first straight lever E, the second sliding lever f (also marked 2) touches the third straight lever E, dac. The pins f2 bear an exactly-similar relation to the alternate straight levers E, beginning with the second-that is, the first pin f2 touches the second straight lever E, the second pin touches the fourth straight lever E, dac., the tenth pin touching the twentieth and last straight lever E. All the levers and pins of the carriage are independent, so that any can be moved without affecting its neighbors. Vhen one or more of the levers f3 on the back side are pushed forward by the action of the straight levers E, they will project over the head of the plungers g, to which they correspond, and will force forward the spring-frame f' with them until they are released, when the sprin gf rame will return them to their normal position. The same applies t-o the sliding levers f on the other side, except that in their case the action is not direct, being communicated by means of the pins f2 and the tilting levers f3, the pins f2 being placed between the plungers, as shown particularly in Fig. 15. It will be observed that when one of these sliding levers f is pushed over the head of a plunger it practically connect-s that plunger with the top F2 of the carriage, so that when the latter is forced down by the action of the piston B2 the plunger g that is so acted upon is forced down with it, making a perforation. Similarly it will be noticed that the plungers that are not so connected when the perforator-carriage F F' F2 is forced down, having a clear space above them, are free to stand on the tape and slide up into that space (or rather they remain stationary while the carriage slides down) until the carriage' rises, when by the action of the bar F3 against the ledge g', with which the head of each pin is provided, they are forced back into their normal position. The plungers g project downward through the carriage into the guideplate K of the die, which is iixed between the standards X2 in the position shown in Fig. 12. The die and guide plates K are perforated with two rows of ten holes each to correspond with the plungers and have a slot K between the two plates for the passage of the tape. The long narrow slot K between the perforations is for the passage of the traveler-pins h5, which engage and draw the tape forward, according to the length of character struck. The space-levers h, ten in number, are mounted on the horizontal axle hX in such a positionthat their long ends project forward between the plungers g (with the exception of the iirst--the left-hand-which lies against the left side ofthe iirst pair of plungers) a little above the guide and die plates, as indicated in Fig. 14. The short ends of these levers set backward, so as to make contact with the straight levers E, which control them. These short ends are each broad enough to make contact with or cover the movement of two of the straight levers E, so that each spacelever h receives the action of and is controlled by one pair of straight levers E. lf either one or both of any pair of straight levers is pushed forward, J[he corresponding space-le ver will be acted upon and tilted up. The space-frame consists of two arms il', fixed on the axle 01X, pivoted on brackets Figs. 1, 2, 7', 9, and 12, and having between their inner ends a small rod h, centered on the left side in the adj Listing-screw h3. Upon this rod is mounted the traveler h2, fitted on the under side with the small pins h5 and at the top with the projection h4, Fig. 9, to engage with the space-levers 7L, which limit its travel. This traveler is connected by means of the connection B7 to the lever BGof the space-engine B3, which actuates it. The spaceframe is set in such a position above the die K that the rod h of the same is just over the center of the slot K and so that the traveler when its pins h5 are engaged in the tape will pass freely under the space-levers h, but when the pins are disengaged will be arrested by the space-levers 7L unless these have been tilted up to let it pass. For the purpose of disengaging and engaging the pins of the traveler with the tape the arms t" (and with them the rod t, on which the traveler is mounted) are tilted up and down by means -of the arm t, which gets its movement from the pin bx, attached to the valve-rod. To receive the action of the traveler-pins, the tape has previously been formed with a continuous central row of perforations, these perforations having the same relative space from center to center longitudinally as the plungers, and therefore the same space as the perforations made by the plungers.

' The small lever j, Figs. 2, 7, and 8, is capable of sufficient backward-and-forwardl motion by the lever m, connecting-rod m', fulcrum 'm2, and lever m3 to the key C O M on keyboard X of machine when such action is desired to interpose the shoulder or broad TOO IOS

IIO

part of said lever between the traveler h2 and the adjusting-screw h3, thus cutting off the space which should separatethe last letter struck from that which follows, producing a combination composed of. the signals cornprised in both. By means of this, as before stated, any conceivable combination of signals may be produced.

Before describing the action of the apparatus in connection with Fig. 12 it will be expedient to explain that the combinations described are those necessary for the perforation of the English Morse code for transmission by the Wheatstone apparatus. The perforation of the tape for use-in connection with the modied forms of transmitter now in use on some lines with the same telegraphic code requires only a different set of teeth and notches (or combination) on the Lshaped levers, producing thereby the necessary combinations of the plungers and spacing apparatus.

I can perfor-ate any of the codes now in coinmon use without alteration in the general action of my machine simply by altering the shape, size, and combinations of the plungers.

The Wheatstone system has been chosen for purpose of illustration as being the most difficult of perforation.

The action of the machine is as followsz' Take,for example, the process of perforating the gure 2, consisting of two dots and three dashes, one of the longest combinations of the English Morse code, and illustrated in Fig. 1l of the drawings. Then the key z is struck, that end of the key-lever Z is depressed, depressing also the frame A, which controls the valve b, the action of which will be hereinafter described after illustrating the process of making the combination of the character indicated. The back end of the key-lever Z being tilted upward by the stroke acts upon the horizontal end of its corresponding L-shaped lever C, tilting forward the long or vertical notched arm of same, the teeth or combination of which in this instance come in contact with the first, second, third, fourth, fifth, eighth, ninth, twelfth, thirteenth, and sixteenth rectangular frames D, as shown in Fig. 12, while the notches allow the remaining frames to remain stationary, these being fwill be seen by reference to Fig. 17, in which the levers f, brought into action in the above combination,are marked by the figure 2. These plungers g are now ready to be driven through the tape; but before proceeding with the perforation it will be necessary to show the action which has simultaneously taken place upon the space-levers h (shown in Fig. 12 and also in plan Fig. 14) and the spaceframe h. As the upright straight levers E were driven forward to act upon the carriage connections they also at same time operated upon the short ends of the first eight spacelevers 7L,'tilting up the long ends (see Fig. 12) to allow the space-frame 7L to travel the proper distance, according to the letterstruck. That this must occur will be seen from the fact that at least one out of every pair in the first eight pairsof the upright straight levers E (counting, as always, from the left) has been pushed forward, and, as already explained, either one or both of any pair coming forward will lift the space-lever corresponding to, that pair. By this time the valve-rod b, acted upon by the lever A6 through the connections A4 A5 from the rigid frame A, has been pushed up nearly to full stroke, tilting up at same time, by means of the connection i', the arms c" t" of the space-frame. This tilting of the space-frame lifts the traveler h2 far enough to free its pins h5 from the center row of perforations in the tape, Fig. 1l, by means of which the tape is drawn forward. At this moment the traveler h2 is in its position of rest against the thin forked part j of the lever j, which intervenes between the traveler and the adj ustin g-screw h3 of the space-frame. When in this position, the projection h4 of traveler h2 is distant exactly one space-that is to say, the distance occupied on the tape by the perforations representing a single dot-from the first space-lever. The traveler 71.2 and the space-levers 7i and the sliding leversf and plungers g of the perforatorcarriage being acted upon as l have indicated, the valve b/ now finishes its upstroke, (and the key its downstroke,) and the compressed air or other iiuid rushing through the ports b2 b3 instantly and simultaneously acts upon the piston B2 of the main engine B and the piston B4 of the space-engine B3, forcing down the carriage by means of the one and by means of the other, through the piston B4 and piston-rod B5, lever B6, and connection B7 to the traveler h2, throws back the traveler toward the right-hand side until it is arrested by the ninth space-lever h, (shown in plan Fig. 14,) Which is the lirst one of its set that has not been lifted by the combination struck. As I have already explained, the sliding levers fin passing over the heads of the plungers g brought these into practically solid contact with the top F2 of the carriage-frame, so that when the perforator-carriage F F F2 was forced down by the action of the piston B2 the points of these plungers g were driven through the tape, and the others, not used in this combination and being free, coming in contact with the resistance of the tape merely stood lightly upon it, their heads entering the clear space between them and the IIO top F2 of the carriage. The perforation being now complete, the key is released and the valve is brought back to its usual position, reversing the action of the pistons B2 B4. As the main piston B2 rises it brings back the perforator -carriage to its former position, withdrawing from the tape the plungers g, which have been used in making the perforation, the other plungers, as has been shown, being forced back into place by the cross-bar F3 acting upon the ledges g. (This perforation as produced upon the tape will be seen by reference to Fig. Il.) The spring-frames f of the carriage now coming into action return the sliding levers and rods or pins ff2 to their former position an d,with the aid of the springframe 7s of the space-levers h, return the uprightstraight levers E, the rectangular fram es D,and the Lshaped lever C to their normal position. Vhen the valve-rod b returns to itsformerposition on the release of the key, its action upon the space-frame is reversed, so that just before the air begins to be admitted again at the port b4 the pins of the traveler once more engage the center pertorations of the tape, and therefore when the action of the engines is completely reversed as soon as the plungers are withdrawn the traveler h2 flies for- Ward (drawing the tape with it) to its former position of rest. It will be seen that the distance which the tape has thus been drawn forward corresponds exactly with the length of the perforated character plus one space. As the perforations in every case begin with the rst lefthand plunger, it will be seen that all letters or characters perforated will show this one space between them unless an extra space or spaces are purposely produced by striking the space-key. As this space-key merely depresses the rigid frame A-that is to say, the valve connection-without producing any combination, it will be seen that only a single space will be made when it is struck.

It it be desired to throw any two or more characters into one combination, it is only necessary while the first key is pressed down to press the key marked C O M (thus interposing the leverj between the returning traveier and its position of rest) and to hold down this combination-key while the other letter or letters are being struck. By this device the separating-space is cut out, causing all the letters so struck to appear as one combination. The purpose of this key is to provide for the perforation of certain signals used in telegraphy, but not with sufticient frequency to warrant giving them a place in the keyboard.

It is sometimes desirable to have the power of adding eXtra spacing arrangements to the machine as described, and for this purpose I have added two views, Figs. 20 and 2l, by way of illustrating my method of performing same. According to Fig. 2O an arrangement is shown for thepurpose ol raising the Whole of the space-levers h, and this is accomplished by a lever-frame y, that acts on the long legs of the space-levers z to raise same when a long space is desired. This lever-frame y is fulcrumed on a bracket y to the side of standard X2 and is connected by a connecting-link y2 to a key-lever ys, the extra key of same being added to the keyboard. Referring to Fig. 2l, this arrangement is for providing a double space at every stroke of space-key when this is desired, and for this purpose I fit to the rod X of the space-frame an adjustable linger or rod g4 for the purpose of lifting the first space-lever h. It will be seen that this letter raises the first space-lever 7L at every stroke of a characterkey, as well as at v the stroke of the spacekey; but as the short est character (th-e letter E) also raises this lever by its own combination it will also be seen that the rod X will not affect the spacing,

except in the case of the space-lever.

Having now described my invention, what I claim as new, and desire to secure by Letters Patent, is-
